Barack and Michelle Obama reminded everyone why they are the ultimate couple goals on Michelle's 54th birthday on Wednesday. "You're not only my wife and the mother of my children, you're my best friend," Barack wrote on Instagram alongside a throwback photo of the two. "I love your strength, your grace, and your determination. And I love you more each day. Happy Birthday."

Not one to be outdone, Michelle responded to her husband's sweet gesture with an equally sweet message of her own. "Thank you [Barack] for the beautiful flowers waiting for me in the office this morning. You're my best friend, biggest fan, and getting notes and flowers from you will never get old," she shared. "And to the many people from around the country who sent cards and posted on social media, you have no idea how much we love hearing from you. I know birthdays can sometimes be bittersweet (54!), but your messages of hope, generosity, and warmth have always reminded me how lucky and blessed we are."

Read on to see the flowers Barack gave Michelle and the countless cards she received from well-wishers across the states on her special day.
